Riding technical XC? The Barzo is the choice of World Champions. How can such an aggressive XC tire roll so fast? The magic starts in the center tread, where we place an alternating ridge design and progressive sipe angles. Cornering duties are handled by the moto-style block knobs, laid out in a proven V-formation. The result is a tire that corners as fast as it rolls, while still offering the protection of a full-depth tread. Rocks and roots? Check. World Championship? Check. - Aggressive XC tread for the most technical terrain - Center tread consists of an alternating ridge pattern with progressive sipe angles - Shoulder tread utilizes a moto-style block knob in a V-formation - Designed for performance in rough and smooth hardpack

Riding your fat bike on ice just got even better with the redesigned Dillinger tread pattern and tubeless compatibility. Carefully positioned studs allow you to rail icy off-camber singletrack with confidence and control, while taller side lugs bring improved cornering in snowy conditions. Dillinger’s center tread is tightly spaced for speed when you need it so you can power up an icy climb and rip down the other side as the studs claw into the slick surface. - Carbide studs grip ice - Braced side lugs for improved cornering - Tubeless ready - We design 45NRTH tires for extreme winter cycling applications. We do not recommend this product be used with power assist bikes as the additional torque and system weight can lead to pre-mature casing wear and stud loss.
